Hydrothermal synthesis of nanostructured β-LaS2 thin films

Electrochemical behavior of hydrothermally synthesized porous groundnuts-like samarium oxide thin films

“…Yadav et al [4,29] synthesized lanthanum oxide films by spray pyrolysis and chemical bath deposition methods and observed porous honey comb-like and rod shaped morphologies, respectively. Ghogare et al [30] prepared lanthanum sulfide thin film by hydrothermal method and obtained nanopetals-like porous morphology. Patil et al [29] obtained cinnamon-like lanthanum telluride thin films by chemical bath deposition method.…”

Preparation and application of rare earth sulfides

“…过分子之间的非共价键力的作用得到稳定的分子聚集 体, 从而得到稀土硫化物的制备方法 [67] . 黄剑锋和侯 艳超等 [57] ; (b) SILAR法合成α-La 2 S 3 薄膜的原理图 [60] (网络版彩图) 液相反应法中, 水热法与溶剂热法类似, 材料尺寸 和形貌控制简单有效, 工业应用成熟 [48] , 但也存在反 应周期长、需要高温高压、对设备的依赖性比较强等 问题; 共沉淀法具有成本低、工艺简单、易于控制、 合成周期短等优点, 但沉淀剂的加入可能会造成团聚 或组成不够均匀等问题; CBD与SILAR具有成本低、 操作简单的特点, 可控性好、材料损失少, 且在沉积 过程中不需要高质量的靶材、衬底和真空度, 还可以 方便地在金属、半导体、绝缘体、塑料等各种衬底上 大面积沉积薄膜, 性价比较高 [63] ; 液相自组装法制备 温度不高于100℃, 所制备薄膜通常具有结构均一, 排 列紧密, 厚度、形态可控等优点 [67] . 总而言之, 与其他 方法相比, 基于溶液的液相反应法通常具有成本低、 操作方便、尺寸和形貌可控、灵活性高等优点.…”

Chelating agent and substrate effect on hydrothermal growth of Yb3+/Er3+ doped NaYf4 film

“…Hydrothermal method has been a popular [24][25][26] technique for thin-film deposition on various substrates, for example, deposition of Sb 2 S 3 on indium tin oxide [27], high quality nanocrystalline CdZnS film on plain glass slide [28] and β-LaS 2 on stainless steel [29]. Also, the hydrothermal process is simple to use and enables the formation of highly crystalline films, with potential for large scale preparations, in a fewer number of steps as compared to other techniques [30][31][32].…”
